GRIP 'DUMB-BELL.

Specification of Letters Patent.

Patented May 14, 1912.

Application filed June 29, 1911. Serial No. 635,924.

To all whom it may concern:

Be it known that I, JOHN CHARLES KoRrrrI, a citizen of the United States, and a resident of the city of New York, borough of the Bronx, in the county and State of New York, have invented a new and Improved Grip Dumb-Bell, of which the following is a full, clear, and exact description.

The invention relates to physical exercisers, and its object is to provide a new and improved grip dumb-bell, arranged to combine a dumb-bell with a hand grip exerciser, with a view to provide the desired weight and to cause an alternate tension and relaxation of the muscles of the hand, wrist and arm when used for a physical exerciser, and to permit of increasing the weight when it is desired to exercise with the device in the form of a dumb-bell without the grip exerciser.

For the purpose mentioned, use is made of a dumb-bell, a grip and a spring connecting the said bell and grip with each other.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a side elevation of the grip dumb-bell, parts being in section; Fig. 2 is an elevation of one end of the same; Fig. 3 is a side elevation of the exerciser arranged as a double-weight dumb-bell, parts being in section; and Fig. 4 is a cross section of the same on the line 4-4 of Fig. 3.

The exerciser illustrated in Figs. 1 and 2 consists essentially of the dumb-bell A, a hand grip B and a spring 0 connecting the dumb-bell A with the hand grip B at one end thereof. The dumb-bell A consists of a handle A and the bells A A, of which preferably one, the bell A is provided with a radial cut-out portion A*, and the handle A is provided with a longitudinal bore or recess A opening into the cut-out portion A*. The spring 0 is provided with a coil C and terminals C C of which the terminal C removably engages the bore or recess A, while the terminal C engages a recess or bore B formed in the hand grip B. The terminal C is preferably provided with a bend or kink (see Fig. 1) so that when the terminal is driven into the bore B, the bend or kink firmly engages the wall of the bore B to hold the grip against accidental displacement. A portion of the coil C extends within the recess A thus holding the spring C against transverse movement and thereby maintaining the dumbbell A and the grip B in the desired relative position, for convenient engagement with the hand when exercising, the user then taking hold, with the palm, of the handle A, and the grip B with the fingers. When this is done, the operator can swing the grip B toward the dumbbell A, thereby placing the spring C under tension, and when releasing the pressure the spring returns the grip B in an outward direction away from the dumbbell A.

In order to limit the swinging motion in an outward direction of the grip B relative to the dumb-bell A, use is made of a stop 1), preferably in the form of a rod provided at its ends with eyes D, D of which the eye I) engages the terminal C in the cutout portion A*, while the eye I) engages the terminal C adjacent the recessed end of the grip B. It is understood that by the use of the device sufficient weight is provided by having the dumb-bell A, and at the same time an alternate tension and relaxation of the muscles of the hand, wrist and arm is had by the user alternately pressing the grip B and releasing the same.

It is understood that two of the exercisers described are usually made use of by a per son exercising simultaneously with both hands, and when it is desired to use the exerciscrs as dumb-bells only, the terminal C of the spring C is drawn out of the bore A so as to permit using the dumb-bell A by itself. It more weight is desired the two dumb-bells A, which belong to a pair of exerciseis, are connected with each other, as indicated in Figs. 3 and -'l, by engaging the cut-out portion A" of one dumb-bell with the handle A of the other dumb-bell so that the two dumb-bells are interlocked and can be readily taken hold of in one hand by the user for dumb-bell exercises.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. An exerciser, comprising a dumb-bell, a grip spaced from the dumb-bell, and a spring connected at its ends with the said dumb-bell and grip at one end thereof, the portion of the spring intermediate the ends of the dumb-bell and grip forming a fulcrum to allow the dumb-bell and grip to swing toward and from each other.

2. An exerciser, comprising a dumb-bell having a longitudinal bore, a grip having a longitudinal bore, and a coil spring having terminals engaging the said bores to connect the dumb-bell and grip with each other.

3. An exerciser, comprising a dumb-bell, a grip, a spring connecting the said dumb bell and grip with each other at one end, and a stop on the spring for limiting the opening movement of the dumb-bell and grip. V

4:. An exerciser, comprising a dumb-bell having a longitudinal bore, a grip having a longitudinal bore, a coil spring having terminals engaging the said bores to connect the dumb-bell and grip with each other, and

a stop having hooks at its ends engaging the said spring terminals to limit the opening movement of the said dumb-bell and grip.

5. An exerciser, comprising a dumb-bell having a longitudinal bore, a grip having a longitudinal bore, and a coil spring having terminals engaging the said bores to connect the dumb-bell and grip with each other, the spring terminals for the grip having a kink to hold the grip against accidental displacement.

6. An exerciser, comprising a dumb-bell provided with a cut-out portion in the bell and having a bore in the handle, a grip having a bore, and a coil spring extending in the said cut-out portion and having its terminals engaging the said bores.

7. An exerciser, comprising a dumb-bell,

said cut-out portion and having its termi- '40 nals engaging the said bores, and a stop having eyes at its ends, one oi the eyes engaging the dumb-bell terminal of the spring at the said cut-out portion and the other end engaging the grip terminal of the spring adjacent the end of the grip.

8. An exerciser, comprising dumb-bells having cut-out port-ions in the bells, the cut-out portion of the bell of one of the dumb-bells being adapted to engage the handle of the other dumb-bell.

9. An exerciser, comprising a pair of dumb-bells having radially cut-out portions in the bells, the cut-out portion of the bell of one of thedumb-bells engaging the handle of the other dumb-bell to form a single exerciser of the pair of dumb-bells.

10. An exerciser, comprising a dumb-bell, a grip, and a spring connecting the said dumb-bell and grip with each other at one end, the spring forming a fulcrum for the dumb-bell and grip to swing toward and from each other.

In testimony whereof I have signed my name to this specification in the presence of tWo subscribing witnesses.
